Abstract
Motion detection is based on picture signal value comparisons between picture elements (P) in consecutive, interlaced television pictures (n-2, n-1), (n, n+1), (n+2, N+3), motion or no motion, respectively, being determined in dependence on the fact whether comparison results exceed or do not exceed a threshold value. Changes in picture information between movie pictures (MP1, MP2, MP3) can negatively influence the telecine television motion detection if they make use of a preceding and a subsequent television picture. To prevent this, an instantaneous picture element (P1) in a first field (n) of a television picture (n, n+1) is compared with a number (P4, P5, P6, P7) of surrounding picture elements in a second field (n+1) and an instantaneous picture element (P11) in the second field N+1) is compared with a number (P14, P15, P16, P17) of surrounding picture elements in the first field (n).
